CHECK-RbWER FOR CORN-PLANTERS.

SPECIFICATION forming part of Letters Patent No. 298,003, dated May 6',1884.

1'0 all whom it may concern Be it known that I, CHARLES S. LooKE, acitizen of the United States of America,-residing at Joliet, in thecountyof Will and State of Illinois, have invented certain new anduseful Improvements in Check-Rowers for Corn-Planters, of which thefollowing is a specification, reference being had therein to theaccompanying drawings Figure l is a plan View; Fig. 2, a cross-sectionof the shake-bar attachment; Fig. 3, a longitudinal section; Fig. 4, aside view of the bracket for attaching the attachment to the planter;Fig. 5, a side View. of a portion of the Y-shaped levers; Fig. 6, aperspective view of the seat supporting the frame of the attachment;Fig. 7, a perspective view of the plate by means of which the attachmentis bolted to the planter, and Fig. 8 a side View of theclamp forattaching the connecting-rod c to a metal shake-bar.

This invention relates to improvements in check-rower attachments forcorn-planters, and is designed more especially as an improvement on theinvention described inLetters Patent No. 280, 641, granted to me July 3,1883.

The object of the invention is to improve the means employed for guidingthe knotted cable, in convenient means for securing the attachment tothe frame of the planter and render it more adjustable to fit anyplanter, and in certain other novel devices and combination of devices,as will be described and claimed.

Referring to the drawings, H represents the main frame of theattachment, which rests on the seat-plate F, (shown more clearly inFigs. 3, 4, and 6,) which plate in turn is supported on the outer end ofthe bracket-arm E. The frame H is provided with a slot, F, through whichpasses the bolt E to secure the frame H to the bracket-arm E, as shownin Figs.- 3 and 4. The slot Fpermits horizontal adjust ment or movementof the frame H on the plate. F by loosening the nut of the bolt E Themeeting faces of plate F and bracket-arm E are provided withcorresponding radial serrations, which mesh with each other when the nuton bolt' E is screwed up tightly for the purpose of holding the parts inposition. The opposite end of bracket-arm E attaches to Applicationfiled January 29, 1s 4. (N0 model.)

plate A in a similar manner by means of the bolt E, as shown in Fig. 4.By this means of connecting the attachment to the planterframe A it maybe adjusted and fitted to any I and emerges from the machine, theseseveral sheave-wheels answering the purpose named much better than theguides provided in the Letters Patent referred to. Frame H has castintegral with it the segment-frame K,which is covered by a like-shapedplate, J, which two plates are held together at one side by the bolt orrivet J and a pair of dowel-pins, one on either side :of said bolt.Between these two plates is located a Y-shaped lever, P, pivoted at V,as shown in Fig. 1, which lever is vibrated from one side'to the otherby means of the knotted wire as it passes through between the two halvesor parts in precisely the same manner as is described in said formerpatent, and said Y-shaped. lever is constructed the same as is describedin said patent, except that one of its outer ends or corners terminatesin a pair of curved arms, P P, which are bolted together by means of abolt and nut,,as

trunnions Z to the segment-plates J and K,

one in each plate, as shown in Fig. 3, and secured therein by washers Tand T, secured on the ends of said trunnions by means of the bolts 1;and o. The plates J and K, hold the two halves of lever P separated justfar enough for the cable W to pass freely between, but to 9 7 The bow ofsaid arms exclude the ball \V. The manner in which the balls \V of saidcable oscillate or vibrate said lever is fully set forth in said formerLetters Patent, and hence need not be described here. The lever P isconnected with the shake-bar B of the planter by means of the link S,lever L, and connecting-rod c, as shown in Fig. l. The shake-bar B andconneeting-rod c are connected as shown in Figs. 1 and 2, and such meansof connection form one new feature in this invention. The shakebar B isprovided on its upper surface with the plate D, attached thereto bymeans of a screw at each end. Said plate is provided with elevatedsides, which terminate in inwardly-projecting flanges, as shown in Fig.1, which flanges do not quite meet, so as to leave a slot or openingbetween them. A sliding plate. D, rests therein, and is provided with acentral downwardly-proj ecti ng rib that slides between said flanges, asshown in Fig. 2.

- Plate D is provided on its upper surface with ing plate D theconnecting-rod 0 can be adjusted along 011 the shake-bar B, as may bedesired, to regulate the drop.

\Vhen the machine or planter has a metal shake-bar, as shown at B inFig. 8, the clamp a (shown in said Fig. 8) may be used, theconnecting-rod c attaching to the pin 3 and the clamp held to theshake-bar by means of 3 5 bracket-arm E, and plates A, the several partsbeing provided with the serrations described, and held adjustahlytogether, as and for the purpose set forth.
